Analysis of the pathogenesis of coronavirus infection caused SARS-CoV-2 indicates a significant impact of hemorheological disorders on its course and outcomes. It is known that chronic cardiovascular diseases are associated with the risk of severe course and lethal outcomes both in COVID-19 and other infectious diseases. Therefore, in each case it is necessary to study the interaction and mutual influence of different components of the treatment program prescribed to such patients.The purpose of this work was to evaluate the effect of coagulation activity on the course of a novel coronavirus infection (COVID-19) and to justify the management of comorbid patients having been received novel oral anticoagulants (NOACs) in previously selected doses according to indications in concomitant somatic diseases.. Total 76 cases of confirmed coronavirus infection in patients who had been received initial therapy on an outpatient basis were analyzed. 26 patients who received NOACs (rivaroxaban, apixaban, dabigatran) made up the main group and 50 - the comparison (control) group in which patients had not been administered any drugs that affect blood clotting until the episode of COVID-19. All patients have been prescribed therapy following the Provisional guidelines «Prevention, diagnosis and treatment of coronavirus infection (COVID-19)» (https://static-0.minzdrav.gov.ru/system/attachments/attaches/).. The number of hospitalizations was significantly fewer in the group of patients who had been received NOACs (19 vs. 66% in the control group). No deaths or cases of severe respiratory and/or renal failure were observed in the main group, while adverse outcomes were noted in 14% of patients who had not been administered these drugs.. Taking NOACs reduces the probability of severe course and adverse outcomes in the development of coronavirus infection caused by SARS-CoV-2, which indicates a significant contribution of coagulation mechanisms to the pathogenesis in COVID-19. There were no indications for drug replacement and correction of anticoagulant therapy regimens in patients who received adequate therapy with oral anticoagulants for treating a non-severe form of coronavirus infection in ambulatory patient settings.

Clarithromycin is a commonly prescribed antibiotic associated with higher levels of direct oral anticoagulants (DOACs) in the blood, with the potential to increase the risk of hemorrhage.. To assess the 30-day risk of a hospital admission with hemorrhage after coprescription of clarithromycin compared with azithromycin among older adults taking a DOAC.. This population-based, retrospective cohort study was conducted among adults of advanced age (mean [SD] age, 77.6 [7.2] years) who were newly coprescribed clarithromycin (n = 6592) vs azithromycin (n = 18 351) while taking a DOAC (dabigatran, apixaban, or rivaroxaban) in Ontario, Canada, from June 23, 2009, to December 31, 2016. Cox proportional hazards regression was used to examine the association between hemorrhage and antibiotic use (clarithromycin vs azithromycin). Statistical analysis was performed from December 23, 2019, to March 25, 2020.. Hospital admission with major hemorrhage (upper or lower gastrointestinal tract or intracranial). Outcomes were assessed within 30 days of a coprescription.. Among the 24 943 patients (12 493 women; mean [SD] age, 77.6 [7.2] years) in the study, rivaroxaban was the most commonly prescribed DOAC (9972 patients [40.0%]), followed by apixaban (7953 [31.9%]) and dabigatran (7018 [28.1%]). Coprescribing clarithromycin vs azithromycin with a DOAC was associated with a higher risk of a hospital admission with major hemorrhage (51 of 6592 patients [0.77%] taking clarithromycin vs 79 of 18 351 patients [0.43%] taking azithromycin; adjusted hazard ratio, 1.71 [95% CI, 1.20-2.45]; absolute risk difference, 0.34%). Results were consistent in multiple additional analyses.. This study suggests that, among adults of advanced age taking a DOAC, concurrent use of clarithromycin compared with azithromycin was associated with a small but statistically significantly greater 30-day risk of hospital admission with major hemorrhage.
